Liquidambar styraciflua (Sweetgum)

A genuinely tough shade tree confirmed resistant to fire, heat, drought, soil compaction, deer, and rabbits, sweetgum also serves as a confirmed larval host for the Luna Moth - delivering both landscape durability and real ecological weight in a single specimen tree.

Species Overview

Liquidambar styraciflua, or sweetgum, is a large deciduous tree native to the eastern United States, frequently found in wet river bottoms, swamps that flood, and drier uplands. It typically grows 60 to 100 feet tall, with distinctive star-shaped leaves that turn vibrant shades of red, orange, and yellow in fall, and produces distinctive spiky seed pods known as "gumballs."

Application

• Large shade tree plantings - confirmed resistant to fire, drought, and compaction

Planting Guidance

• Spiky seed pods ("gumballs") drop between December and April and create litter/tripping hazards in pedestrian areas - worth flagging for high-traffic landscape use.
